Abstract (en)
A motor (100), a rotor (50) and a sleeve (54) are provided. The motor (100) includes a stator (10) and a rotor (50) which includes a shaft (51), a rotor core (52), a sleeve (54), a commutator (53), and a rotor (50) winding wound on the rotor core (52). The sleeve (54) is arranged between the rotor core (52) and the commutator (53). The sleeve (54) includes a first end portion (544) close to the commutator (53), a second end portion (542) close to the rotor core (52), and a middle portion (543) therebetween. An outer diameter (D2) of the first end portion (544) is smaller than an outer diameter of the middle portion (543), and the outer diameter of the middle portion (543) is smaller than an outer diameter of the second end portion (542). An end of the commutator (53) close to the sleeve (54) has a groove (534), and the first end portion (544) of the sleeve (54) is placed in the groove (534). The rotor (50) has a good seismic performance.
